Take a look, what kind of knife is this? Is it an ordinary milling cutter?





  Looking at the attached view again, the original difference from the ordinary milling cutter is that there are a few more grooves on the upper handle.




  Installed on the knife row, it produces internal cooling, and its effect is self-evident. International first, nowhere to buy, just make it yourself.




  The threaded hole on the side of the processing step is too short, what should I do? It takes a lot of money to buy it, and you have to wait for long time...




  A self-made extension pole, simple and practical!!!




  Is this an ordinary anti-scraper row? YES!




  A hole is punched in the middle and a slot is opened in the front (see the previous picture) to become an anti-scraper row with internal cooling. Slightly improved, the efficiency is greatly improved!
